CARRIER FOR WASHING-BOWLS.

Specification of Letters Patent.

Application filed May 25, 1911.

Patented Oct. 3, 1911.

Serial No. 629,272.

To all whom it may concern:

Be it known that I, CHARLES G. SARGENT, a citizen of the United States,residing at Westford, in the county of Middlesex and State ofMassachusetts, have invented a new and useful Carrier for Washing-Bowls,of which the following is a specification.

This invention relates to a washing machine capable of general use, butparticularly adapted for washing wool, and it is more especiallydesigned to be applied to that type of wool washing machine in which areciprocatory rake is employed for moving the wool up to the dischargeend of the bowl in an intermittent manner.

The principal objects of the invention are to provide for removing thepile of wool left by the rake in a substantially uniform manner insteadof in an intermittent manner as has been the case heretofore; to providemeans whereby the pile of fibrous material is acted upon gradually, thetop being removed firstand then the lower portions; and to provide animproved form of table for receiving the wool at the discharge end ofthe bowl, and a chute for delivering it.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which the figureis a side view of a wool washing machine partly in longitudinal centralsection, showing a pre ferred form of this invention.

The invention is shown as applied to a well-known type of wool washingmachine in which the bowl 1 is provided with a reciprocatory rake 2 forintermittently moving the wool up to the discharge end of the bowl, soas to be discharged therefrom between the rolls 3. A driving shaft 4 andpulley 5 and operating mechanism 6 for the rake are shown, but any othertype can be used. The usual links 7 and counter-weights 8 are indicated.In this case, however, the

false bottom of the bowl is provided at 13 with a table for supportingthe wool slanting upwardly preferably in concave form. From the upperend of this table the. chute 14 slants downwardly to the press-rolls 3.

This form of the parts assists in producing the effects hereinafterdescribed. As ordinarily operated these rakes intermittently depositlarge quantities of wool at their feeding ends and then draw back to getanother load. The result of this is that the usual carrier which is madeto operate uniformly gets a big lump of wool when it is first depositedin reach of it and feeds it to pen to be taken up by the first teeththat strike it after it is deposited at this point. The result of thishas been that the press rolls are subjected to unnecessarily rough usagetaking a big quantity of wool at one time and then running almost idly.Another result of course is that the wool which is brought through firstis not operated upon by the press rolls with the same uniformity as thesmall quantities that come through later. In order to overcome thesedeficiencies, the construction of table 13 and chute 14 is provided ashas been described, and in addition to this means is provided whereby assoon as the wool is deposited by the rake in position on the table 13only the parts at the top of the pile are first carried over on thechute 14 and then gradually those parts lower down are taken over sothat the wool being fed to the rolls is substantially of a uniformquantity throughout the entire operation of the rake. For this purpose asprocket wheel 15 on the shaft 4 drives a sprocket wheel 16 of equaldiameter by a chain 17. The wheel 16 and a cylinder 18 are fixed on acarrier shaft 19, which is located at the discharge end of the rake atthe delivery end of the bowl and over the table 13. This constitutes arotary carrier for taking the wool deposited by the rake feeding it upthe incline 13 and out on the chute 14. This carrier is provided withteeth 20 of varying lengths. The teeth on one side are longer than thoseon the other side and the intervening teeth vary gradually from theshortest to the longest. In this way it will be seen that the ends ofthe teeth are arranged eccentrically with respect to the shaft 19. Inaddition to this the cylinder is set at a certain position on the shaftand the shaft is run by the chain and sprockets, so that the short teethwill be just coming into operation when the rake deposits its load underthe cylinder, and the long teeth will come into operation as the rakerecedes and while it is starting forward. In this way the wool is fedover in a more uniform manner and the above mentioned difficulties arenot encountered.

As the harrow is atthe extreme front of the bowl in its lower positionand just starting to move forward, theoretically the least amount ofwool is engaging with the carrier. This mass of wool is increased as theharrow continues in its forward orbit and as this mass increases,succeedingly shorter teeth in the carrier enter the liquor until a timearrives when again the least amount of wool is beneath the carrier whenthe longer teeth, those extending near the false bottoms, are engagingwith the wool.

Although I have illustrated and described a particular embodiment of theinvention, I am aware that many modifications of the mechanismillustrated can be employed for securing these objects without departingfrom the scope of the invention as expressed in the claims. Therefore Ido not wish to be limited to all the details of construction hereinshown and described, but

IVhat I do claim is 1. In a washing machine, the'combination with a bowland reciprocatory means for moving material along toward one endthereof, of rotary means for delivering from the bowl relativelysmallproportions of the material just after it is left at'the end of thebowl by the reciprocatory means, and for delivering larger proportionsthereafter until. the next operation of the reciprocatory means, wherebythe material is delivered in a substantially uniform manner.

2. In a washing bowl, the combination with an inclined chute, a carriertable ex tending upwardly to the upper end of said chute for receivingthe stock, and a rotatable carrier having fixed teeth movable with thecarrier in position to lift the stock along said table over on thechute, which teeth project farther toward the table at one period of therevolution of the carrier than at the other periods.

3. In a washing bowl, the combination with a table for supporting thematerial to be washed, of a rotary carrier for moving the material alongthe table and expelling it from the bowl, said carrier having fixedteeth, the ends of which are eccentrically arranged with respect to thecenter of the carrier.

4. As an article of manufacture, a rotary cylinder for a washing bowlprovided with teeth of unequal lengths.

5. As an article of manufacture, a rotatable carrier for a washing bowlprovided with fixed teeth, the ends of which are eccentrically arrangedwith respect to the axis of the carrier.

6. In a washing bowl, the combination with a reciprocating rake, of arotary carrier located near the end of said rake for taking the materialtherefrom and moving it forward, said carrier having teeth of un equallengths, the shorter teeth being on one side of the axis thereof and thelonger on the other side.

7. In a washing bowl, the combination with a reciprocating rake, of acarrier lo cated near the end of said rake for taking the materialtherefrom and moving it forward, said carrier having teeth of unequallengths, the shorter teeth being on one side thereof, and the longer onthe other side, and means whereby the shorter teeth are brought intoposition to engage the material deposited by the rake when the rakemoves up to its limit toward the carrier and the longer teeth operateupon the material when the rake is drawn back.

8. In a washing machine, the combination of a reciprocatory member fortransferring the material to be washed alongthe bowl thereof, with acarrier arranged at the delivery end of said reciprocatory member andhaving short teeth and long teeth, and means for operating said carrierto bring the short teeth into operative position when the reciprocatorymember is advanced to the extreme position, and to bring the long teethinto operation when it, is retracted.

9. In a washing machine, the combination with a bowl and a reciprocatorymem ber operating therein for transferring material along the bowl, ofmeans for engaging the materialdeposited at the end of the bowl therebyand removing the top of the pile left by said means and then graduallyremoving the lower portions thereof while the first named means is beingretracted.

In testimony whereof I have'hereunto set my hand, in the presence of twosubscribing witnesses.
